To all whom it may, concern.-

Be it known that 1, CHARLES F. MORRISON, of Thompsonville, in the county of Hartford and State of Oonnecticut,have invented certain new and useful Improvements in Feeding Devices for Oarding-Machines, of vwhich the following is a full, clear, and exact detion, whereby any one skilled in the art can make and use the same.

The object of my invention is to provide a simple, direct and automatic feeding mechanism for a carding machine bytlie use of which most of the faults of prior feeding devices are avoided.

- To this end myinvention consists in details of the construction of the several parts of the feed device, and particularly of the condenser, and in the combination of the several parts making up the device as a whole, as more particularly hereinafter described and pointed out in the claims.

Referring to the drawings: Figure 1 is a plan view of a machine embodying my invention. Fig.2 is a detail view in central section through the apparatus.

In prior devices of this class the bat as it comes from the dofler is delivered to one side of the card, from which position it is fed into the next succeeding card by processes which cause the bat to be fed back and forth from side to side onto the apron of the said card, causing a doubling at each side, and the threads made from this portion of the bat are coarse and uneven an'd in most instances go to waste.

In the within application a device is described that feeds the bat directly from one card into the next succeeding card in a-continuous mass, the doubling or folding above referred to being entirely dispensed with.

In the accompanying drawings only so much of a carding machine is shown as directly relates to my invention, the letter adenoting the dofit'er and b the doifer knife.

A frame 0 is provided extending from one card to the other, and in this frame mounted in suitable bearings are arranged the rolls 61 around which extends the endless apron e. This apron extends from underneath the doffor to the feed rolls f of the next succeeding card and is moved at the required rate of speed, by power and suitable connecting mechanism derived fromeither'of the-cards,

to feed the 'bat in the-desired quantityto the feed rolls f. Immediate] yin front of the doffer, and preferably secured to the framec, there is provided a guard g arranged obliquely to the plane of movement of the bat as it falls perpendicularly from the dofier, this guard preventing the bat from falling underneath thedoffer, and also serving as a partial support for the bat which catches on the slanting surface of the :guard and folds back and forth upon itself in a direction lengthwise of the frame until a sufficient quantity has gathered on the guard to .cause the bat to -fall from its own weight and the movement of the apron onto the apron. On the side parts of the frame care secured the brackets h, and these brackets are preferably madeadjustable in adirection lengthwise of the frame. The condenser lever is pivotally supported on these brackets h,.and itis arranged transversely across the-frame in'such position as to allow the condenser to project forward and downward toward that part of theapron that is near the doffer-and the point'where the bat is fed as it is taken from the doffer. This condenser lever is preferably composed of blade 2' is immediately secured. Theseparts are so connected to each other that the arms lieat an angle and form a'speciesof bent lever, so that when a rockingmovementof the lever is had on the pivotsby means of which the condenser lever is attachedto the brackets -h a peculiar swinging movement is imparted by suitable mechanism to the condenser blade so that it presses upon'the'bat, flattensand condenses it as it is-drawn forward from the card by the apron.

The stock is removed from the carding machine by the comb in a somewhat thick sheet, and it is in order to flatten down and equalize the thickness of this mess that the condenser has a peculiar movement forward and back, as well as up and down, the flattening out and backing the stock by this movement in a curved line diagonally to the plane of the combing apron on which the bat falls from the comb forming an essential part of my invention.

The condenser supports a supplemental blade j borne on the ends of the arms j that extend backward from the under part of the condenser or from the condenser lever, and this blade is so arranged that in the operation of the main blade the supplemental blade is given a vertical reciprocation causing it to strike upon the bat at a point somewhat re moved from the main blade and gives an additional aid to the forming of a hat of regular density. 011 the end of this supplemental blade j are projections 70 that strike the bat close to the edge near the side parts of the frame that supports the apron and operates to correct any irregularity of the edge of the bat that may have passed either of the preceding blades. The main blade of the condenser is preferably V-shaped with the point somewhat rounded and projecting close into the angle formed where the guard g approaches the apron e.

To the condenser lever, or to an arm projecting therefrom, is pivotally connected the rod 1 at one end, while the other end is connected to the crank m that is turned as by means of a belt (not shown) passing over a pulley 071; this serving as a means for reciprocating the condenser, or any other suitable means for causing this reciprocation of the condenser may be employed without departing from my invention, the essential feature being the movement back and forth of the condenser to properly pack or condense the bat as it comes from the dolfer.

The endless apron e is of a width that enables it to fit quite closely between the side parts of the frame which serve as a gage to regulate the width of the bat and the direction of its movement as it passes along on the endless apron into the feed rolls of the next succeeding card in a flat sheet practically of the same width as that at which it came from the preceding card and even throughout as to density and arrangement of fibers.

On side parts of the frame and immediately in front of the doffer knife is supported a guard b transversely of the frame in such a position that the main blade of the condenser in its swinging movement sweeps past the guard close to its lower edge, removing any surplus fiber that may have adhered to the blade.

I claim as my invention 1. In combination with a carding machine,

a frame bearing an endless apron, a reciprocating condenser supported in operative relation to the card and the apron, and a guard located in front of the condenser blade adjacent to the doifer, all substantially as described.

2. In combination with a carding machine, a frame bearing an endless apron movable thereon, a condenser pivotally supported on the frame having a blade arranged transversely of and over the apron, a guard fixed transversely of the frame between the dolfer and the condenser blade, and a clearer supported above and adjacent to the path of movement of the condenser blade, all substantially as described.

8. In a feeding device for carding machines, a frame bearing an endless apron movable thereon, the adjustable bracket secured to the frame, the condenser adjustably pivoted to the brackets, the adjustable pivot, the guard located in front of the condenser blade and between it and the doifer, and aclearer located above and adjacent to the path of movement of the condenser, all substantially as described.

4. In a feeding device for carding machines, an inclined frame highest at its outer end and supporting an endless apron movable on said frame, the condenser lever pivotally supported on the frame and bearing a blade secured to the levers by means of the condenser arms, and the supplemental condenser blade projecting outward from the arms, the guard located in front of the condenser and the clearer fixed above the condenser and adjacent to the path of movement of the blade, all substantially as described.

5. In a feeding device for carding machines in combination, the inclined frame, the endless apron supported and movable thereon, the apron driving mechanism, the condenser lever pivotally supported on the frame, the condenser blade secured to the lever, the supplemental blade extending rearwardly from the main blade and bearing the downward extending projections, the guard located in front of the condenser, and the clearer fixed above the condenser and adjacent to the path of movement of the latter, all substantially as described.
